Summary: this page describes how to manage display preferences for CAST Imaging.


The Preferences option is available in the user menu:

It enables you to set various system wide display preferences as described below:

When you make a change to an option, ensure you use the Update button to save the preferences.


Landing Page

Allows you to select the default application landing page. CAST Imaging provides the following landing page options:

  • Welcome Page: This is the default setting out of the box providing you with a dedicated "Welcome Page" for your application. The Welcome Page shows details about the application (total number of objects, LOC value, number of transactions etc.) and provides buttons to load tailored views of the items in the application (e.g. : all Database Tables, all Modules etc.).
  • Imaging MenuThis option will direct you to the application detail whenever the application name is selected, therefore bypassing the Welcome Page.

Preferred Language

Allows you to select a system wide language. Out of the box, CAST Imaging will use English (en_US) as the default language display option for all menu options and texts. CAST Imaging also provides the following language options:

  • English (en_US)b
  • Chinese (zh_CN)

Saved views drill mode

This option governs how Saved views are accessed:

List mode

In List mode, Saved views are listed in the drop down to the left of the main view:

Graph mode

In Graph mode, Saved views are displayed in vignettes in the main view:

Level Drill Mode

This option governs how the double-click drill down action behaves for Level 5 views:

Children only (default)This option is the default drill down behaviour. Only direct children of the selected node will be displayed at Objects level. Note that if child objects can be "grouped by communities" then this layout will always be used, i.e. the direct children of the selected node will be grouped together by community.
Children + caller/calleeWhen selected, direct children of the selected node and any objects calling or called by the selected node will be displayed at Objects level. Note that if the child objects and their caller/callees can be "grouped by communities" then this layout will always be used, i.e. the direct children of the selected node and their caller/callees will be grouped together by community.

Preferred graph layout

Allows you to select the preferred default graph layout mode for the following scopes:

When set, the corresponding option in the chosen scope will reflect the change:

Maximum number of views

This option sets the maximum number of views (vignettes) that can be created using the  icon (see User Guide - GUI - Menus and Icons):

Node Limit / Edge Limit

A progressive rendering mechanism exists so that very large and complex displays can load in a satisfactory period of time. When accessing a node (double click) which contains more than 1000 child nodes, or more than 2000 edges, the progressive rendering system is invoked in order to avoid situations where the rendering process locks the browser. Portions of the full graph are displayed progressively in steps and when this occurs, a message will be displayed as shown below - you can click this button to stop the progressive loading (you can find out more in User Guide - GUI - Menus and Icons):

≥ 2.10.0

≤ 2.9.0

The options allow you to modify the thresholds at which this progressive rendering system is invoked, if required. They are set by default to:

You may need to empty your browser's cache and reload the page to view changes to the thresholds.

Notify objects count

This option sets the threshold (default = 10000) at which a popup is displayed when:

  • drilling down on a node in any view
  • or switching to the Objects view via the Investigate panel

The popup warns that the resulting view contains a large number of objects - i.e. above the threshold - and that the view may take some time to fully load. Various options are then offered:


In these releases, the popup gives you the opportunity to cancel the action or to either download a .CSV file containing details about the list of objects in the resulting view or to proceed with displaying the view.

  • Download is displayed when clicking an object at Objects level, specifically for large Transactions and Data Call Graph items
  • Proceed is displayed when clicking a node in Level 5.

Alternatively you can click the Search Objects button to search for and display specific objects from the resulting view. The Search Objects window functions in a similar way to the Global (all application) Search - see User Guide - Search for items:

Path finder

Available only in CAST Imaging ≤ 2.11. In more recent releases, the Path Finder feature is enabled by default.

This option enables/disables the Path Finder feature.

Application walkthrough (animation)

This option toggles the application walkthrough feature. By default, this feature is enabled and when enabled, an animation is displayed when switching between layers. If you do not require this animation, disable the option:


This option is only visible to users with the ADMIN role and determines only whether a user with the ADMIN role can use the Tutorial feature. If you want to enable the Tutorial for a non-ADMIN user, please see Admin Center - Users panel.

This option enables or disables the Tutorial for ADMIN users. By default it is disabled. When enabled as shown below, the Tutorial will be displayed on login to CAST Imaging:

In addition the Tutorial menu item will be displayed in the bottom left corner of the screen:

Welcome Guide

The Welcome Guide option works in conjunction with the User Guide - GUI - Welcome Page. When the Welcome Guide option is enabled (default position), navigating from a tile in the Welcome Guide will automatically display an explanation of the selected tailored view in a pop-up in the bottom left corner. When the Welcome Guide option is disabled, the explanation pop-up is never displayed.

For example, when the option is enabled, clicking Frameworks in the Welcome Page displays the explanation of this tailored view in a pop-up in the bottom left corner:

Objects export

Enables the Download button in the global search box allow you to download to .CSV file all the matching items in the list which have a tick in the checkbox. See also User Guide - Search for items:

Advanced Search Configurations

In ≥ 2.13.3, changes have been made to the behaviour of the Advanced Configurations options available in all search dialogs:

  • Changing an option in one search dialog will make the same change in all the other search dialogs - i.e., enabling the "Regex pattern" option will enable it across all search dialogs.
  • Changing an option in a search dialog will override the default options set in the Preferences dialog - i.e., if the "Regex pattern" option is set to "disabled" in the Preferences dialog and if it is subsequently changed to "enabled" in a search dialog, all other search dialogs will also have "Regex pattern" option set to enabled, regardless of the option set in the Preferences dialog.
  • Changes made in a search dialog are valid only for the current user's session - as soon as the user logs out the changes revert to the default options set in the Preferences dialog.

This section allows you to set default search options for the following features

The All Application search (see User Guide - Search for items)

The filter search list in the Transaction and Data Call Graph scopes

Saved view search

Application to Application Dependencies scope

Path Finder feature

Add Linked Objects feature

Changing an option in the Preferences panel will automatically reflect in the All Application search or in the Transaction/Data Call Graph filter search, except where an option has been manually changed in a search dialog (this change will override the option set in the Preferences dialog for the duration of the user session), for example:

Regex pattern option enabled in Preferences

Regex pattern option now enabled when using the All Application search

Access All Application search:

Regex pattern now enabled:

Download sample tutorial

This option links directly to the CAST Extend entry for the sample tutorial application, allowing you to download this if necessary: See User Guide - Tutorial for more information.
